Aerosol automatic fire extinguishing device cabinet type hanging electrical fire special rapid response maintenance free

Description :

  Aerosol automatic fire extinguishing device is an efficient fire extinguishing equipment based on the principle of chemical inhibition, mainly used to extinguish initial fires in enclosed or semi enclosed spaces. It interrupts the combustion chain reaction by releasing micron sized solid particles and gaseous substances, making it particularly suitable for places such as power distribution rooms, cable tunnels, server rooms, etc. where water or gas fire extinguishing agents are not suitable. This device can quickly start in the event of a fire, without the need for external power drive. It relies on internal thermal sensors to sense temperature and automatically trigger, effectively solving the problems of slow response, excessive residue, and difficult cleaning in traditional fire extinguishing systems. It is a key defense line to ensure the safe operation of electrical equipment.

  The aerosol automatic fire extinguishing device usually adopts a stainless steel or galvanized steel plate shell, which has good corrosion resistance and mechanical strength. The core fire extinguishing agent is S-type or K-type hot aerosol, and the particle diameter after spraying is less than 10 microns, which will not cause secondary damage to precision electronic components. The implementation standards comply with the requirements of GB50370 "Design Code for Gas Fire Extinguishing Systems" and GA499.1 "Hot Gas Aerosol Fire Extinguishing Devices". Common specifications include a design fire extinguishing concentration of 5g-20g/m ³, a starting temperature generally set at 170 ℃± 5 ℃, a working pressure of atmospheric storage, no need for high-pressure containers, reducing safety risks during transportation and installation, and possessing long-term stability. The shelf life can usually reach 5-10 years.

  When selecting an aerosol automatic fire extinguishing device, it is important to consider the volume, sealing, and type of protected area. It is suitable for relatively enclosed spaces such as control cabinets, distribution boxes, small computer rooms, etc., and has limited effectiveness for completely open or highly ventilated areas. Compared with water spray systems, it has the advantages of no water stain loss, good insulation performance, and easy installation; Compared with heptafluoropropane, it does not require complex pipeline networks, does not require steel cylinder rooms, has lower cost, and is easy to maintain. When purchasing, it is necessary to confirm whether the installation method of the device (hanging, cabinet or wall mounted) matches the on-site environment, and ensure that the protective area is equipped with a pressure relief port to prevent damage to the building structure caused by excessive pressure during spraying.

  When installing an aerosol automatic fire extinguishing device, it should be fixed at the top or above the protective area, ensuring that the nozzle faces the center of the protected object and there are no obstructions within 0.5 meters around it. Daily maintenance mainly includes regular inspections to ensure the appearance is intact, the safety pin is in normal condition, the label identification is clear, and checking whether the fixed bracket is loose. Due to the fact that this device is mostly disposable, the entire fire extinguishing agent component or machine needs to be replaced after spraying. Common fault diagnosis includes misoperation caused by false alarms or failure to start due to aging of thermal sensitive components. It is recommended to conduct a professional inspection every two years and strictly prohibit unauthorized disassembly or modification of the starting mechanism to ensure reliable operation in emergency situations.
